I'm A Celebrity bosses think Kezia Dugdale is a 'massive letdown' and are disappointed with her for 'barely bothering' in the trials, sources claimed.

The 36-year-old was reportedly drafted into the jungle in the hopes that she would spark a political showdown with former politician Stanley Johnson, bond with campmates and show off her 'softer side'.

But producers allegedly feel the Scottish MSP has been 'acting superior' and accused her of giving a lacklustre performance in Saturday's live trial - despite her rumoured six-figure pay package.

Unimpressed: I'm A Celebrity bosses think Kezia Dugdale is a 'massive letdown' and are disappointed with her for 'barely bothering' in the trials, sources claimed

'Kezia has been a massive let down since joining the show last week,' a source told The Sun.

'She hasn't bonded particularly well with other campmates and doesn't see herself as part of that showbiz world, she has been acting superior,'

'Far from coming out of her shell, she hasn't broken from her politician mode once or shown a softer side, letting her personality come through.

Much of this year's series has been politically-themed, from the Number 10 Downing Creek camp set-up to the trials.

Bosses were reportedly hoping Kezia would engage in political debate with former Tory MEP Stanley Johnson - father of foreign secretary Boris - and have been left underwhelmed.

The insider added that chiefs were 'ticked off' that Kezia 'barely bothered' in the series' first live trial, branding her a 'bad sport'.

A close friend of Kezia's told MailOnline: 'Kez was straight off the plane into the jungle and then went four days with just rice and beans after losing the first task.

'Despite all that, she's been an absolute star - repeatedly cracking jokes at Stanley's expense and preforming brilliantly in trials. She struggled with the milkshakes, but has made up for it with the other tasks.

'And she's clearly keeping the camp in order. The other campmates are seeing just how warm, friendly and loving she is. Back home, everyone in Scotland is getting behind Team Kez.'

MailOnline has contacted a representative for I'm A Celebrity... Get Me Out Of Here for comment.

The former Labour boss had to down a pig and ostrich anus concoction in a race against Iain Lee during one task in the live trial.

She also had to neck a foul blended bull penis smoothie but struggled to finish the sickening drink while Iain powered through.

Her performance left presenter Ant McPartlin commenting: 'I have to say Kez gave up there. She gave up. She didn't even try. She's only got herself to blame.'

Kezia lost another trial against Iain days earlier, as they were forced to prove themselves in the politically themed Battle For 10 Downing Creek Bushtucker Trial.

The challenge saw the newbies crawl through two perspex tunnels, made up of five politically-themed chambers with names like 'Sickola Sturgeon' and 'Theresa Dismay', and search for stars nestled between an array of jungle critters.

Despite the camp mates tipping Kezia for success, it was funnyman Ian who reigned victorious - and was crowned Jungle Prime Minister, after bagging all six stars on offer.

It comes as Kezia boasted that the fee she is receiving for appearing in the jungle is in 'no sense small'.

Dugdale, who will be leaving her constituents without an MP for three weeks, defended her decision to appear on the show - pledging to donate her tax-payer funded salary to the Rock Trust homeless charity for the duration of her time away.

Before arriving in Australia, Kezia had already prompted criticism for leaving her constituents behind, while TV and radio presenter Iain hinted at what's to come when he said he was 'basically paid to be annoying.'

Speaking before she arrived in the jungle, Kezia said: 'People have definitely seen me deal with a few rats and snakes in my time.

'I'm tougher than people think I am – you don't get the top of politics without a thick skin but i think the jungle is going to be a lot tougher.'

On the public's reaction, she added: 'I think people's overriding emotion will be, first and foremost, shock. I think there will be a few people angry. They will be angry because they will say I should be doing my day job and I am going to be away. I understand that anger.

'I've seen them be angry over similar things other people have done but I can't help but think that it is an amazing opportunity to talk to millions of people about the Labour Party, its values and how it is different.

'I am not going to talk about politics all the time but it is who I am, what I do and I can't help it... Did I tell anyone beforehand? Other than my partner and office manager, I didn't tell anyone about the show.'
